Beneath the Burning Sun
Agency 1 cost Support Environment
Day. It is Day.
Forced Response: After Beneath the Burning Sun enters play, destroy all Night cards.
Agency characters gain a C icon.
Intervention
Agency 2 cost Event Encounter
If your opponent has put a character into play due to a card effect this turn, reduce the cost to play Intervention by 2.
Action: Put an Investigator character with 3 skill, Willpower, and CCI. At the end of the phase, sacrifice Intervention.
Here's my question, is the Encounter character considered an Agency character that could benefit from BtBS?
My ruling was no because even though Intervention is an Agency Event the card text does not specify the resulting characters'
faction but if that's the case does the Encounter character then have no faction affiliation?
